REPLACING AN OLD PUMP
WARNING – HAZARDOUS VOLTAGE! Disconnect power to pump before working on pump or motor.
Step 1. Drain and remove the old pump. Check the old pipe for scale, lime, rust, etc., and replace it if necessary.
Step 2. Install the pump in the system. Make sure that all pipe joints in the suction pipe are air tight as well as
water tight. If the suction pipe can suck air, the pump will not be able to pull water from the well.
Step 3. Adjust the pump mounting height so that the plumbing connections do not put a strain on
the pump body. Support the pipe so that the pump body does not take the weight of piping or fittings.
WARNING – HAZARDOUS PRESSURE!
Pump body may explode if used as a booster
pump unless relief valve capable of passing
full pump flow at 75 psi is installed.

WARNING – HAZARDOUS VOLTAGE!
Disconnect power to pump before
working on pump or motor.
Step 1. Drain and remove the old pump. Check the old pipe
for scale, lime, rust, etc., and replace it if necessary.
Step 2. Install the ejector kit. Follow the instructions provided
with the kit. Be sure to align the venturi with the top
hole on the front of the pump (see Figure 3).
NOTICE: Always replace the ejector when replacing the
pump in a shallow well installation.
Step 3. Install the pump and faucet in the system. Make sure
that all pipe joints in the suction pipe are air-tight as
well as water tight. If the suction pipe can suck air,
the pump will not be able to pull water from the well.
Step 4. Adjust the pump mounting height so that the plumbing
connections do not put a strain on the pump body.
Support the pipe so that the pump body does not take
the weight of piping or fittings.
Step 5. Run piping from elbow to the household piping. The
discharge piping must be at least as large as the elbow.
You have just completed the well plumbing for your new jet pump system.
INSTALLATION— MODEL XDPM196A3
Step 1. Remove the control valve from the pump body.
Replace it with a 1” NPT close nipple,
a 1”x1” NPT elbow, and (see Figure 1).
Step 2. Install the ejector kit. Follow the instructions
provided with the kit. Align the venturi with the
top hole on the front of the pump (see Figure 6).

2" OR LARGER CASING (FIGURE 5)
Step 3. Mount the pump as close to the well as possible.
Connect the pipe from the well to the pump suction
port, using the fewest possible fittings – especially
elbows – as fittings increase friction in the pipe.
Step 4. Assemble the foot valve, strainer, and well pipe
(see Figure 5). Make sure that the foot valve
works freely.
Step 5. Lower the pipe into the well until the strainer is 5 feet
above the bottom of the well. It should also be at least
10 feet below the well’s water level while the pump is
running in order to prevent the pump from sucking air. Install a sanitary well seal.

DRIVEN POINT INSTALLATION (FIGURE 6)
Step 3. Drive the well, using “drive couplings” and a “drive cap”. “Drive
fittings” are threaded all the way through and allow the pipe ends
to butt against each other so that the driving force of the maul is
carried by the pipe and not by the threads. The ordinary fittings
found in hardware stores are not threaded all the way through
the fitting and can collapse under impact. “Drive fittings” are also
smoother than standard plumbing fittings, making ground
penetration easier.
Step 4. Mount the pump as close to the wall as possible.
Step 5. If one well point does not supply enough water, consider
connecting two or three well points to one suction pipe.
ALL PUMP INSTALLATIONS
Step 6. Install elbows, and suction pipe to the pump (see Figures 5
and 6). Connect the pipe from the well to the pump suction port,
using the fewest possible fittings – especially elbows – as fittings
increase friction in the pipe.
• The suction pipe should be at least as large as the suction port on
the pump (include a check valve – see Figures 5 and 6).
• Support the pipe so that there are no dips or sags in the pipe, so it
doesn’t strain the pump body, and so that it slopes slightly upward
from the well to the pump (high spots can cause air pockets which
can air lock the pump).
• Seal the suction pipe joints with Teflon tape or pipe joint
compound approved for use on PVC. Joints must be air and water
tight. If the suction pipe can suck air, the pump cannot pull water
from the well.
Step 7. Run piping from the elbow to the house- hold piping. The
discharge piping must be at least as large as the elbow.

CONNECTION PROCEDURE:
Step 1. Connect the ground wire first as shown in Page 4. The ground wire must be a solid copper wire at least
as large as the power supply wires.
Step 2. There must be a solid metal connection between the pressure switch and the motor for motor grounding
protection. If the pressure switch is not connected to the motor, connect the ground screw in the switch
to the ground screw under the motor end cover. Use a solid copper wire at least as large as the power
supply wires.
Step 3. Connect the ground wire to a
a) grounded lead in a service panel
b) a metal underground water pipe
c) metal well casing at least ten feet (3M) long
d) to a ground electrode provided by the power company or the hydro authority.
Step 4. Connect the power supply wires to the pressure switch as shown in Page 4.
You have just completed the wiring for your pump. Please go to startup preparations on page 7.

PREPARING TO START THE PUMP – ALL MODELS
CAUTION: Never run a pump dry. Running pump without water may cause pump
to overheat, damaging seal and possibly causing burns to persons
handling pump. Fill pump with water before starting.
WARNING! Never run pump against closed discharge. To do so can boil water
inside pump, causing hazardous pressure in unit, risk of explosion
and possibly scalding persons handling pump.
Step 1. Remove the priming plug from the pump and fill the pump, fill all
piping between the pump and the well, and make sure that all pip- ing
in the well is full (see Figure 7).
Step 2. Replace all fill plugs.
Step 3. Power on! Start the pump. The pump should pump water in two or
three minutes.
Step 4. If you don’t have water after 2 or 3 minutes, stop the pump and
remove the fill plugs. Refill the pump and piping. You may have to
repeat this two or three times in order to get all the trapped air
out of the piping.
Step 5. After the pump has built up pressure in the system and shut off, check
the pressure switch operation by opening a faucet or two and running
Figure 7: Fill Pump Through
Filling Plug
enough water out to bleed off pressure until the pump starts. The pump should start when pressure
drops to 20 PSI and stop when pressure reaches 40 PSI. Run the pump through one or two complete
cycles to verify correct operation. This will also help clean the system of dirt and scale dislodged during
installation.
Congratulations on a successful installation. If you were unsuccessful, please refer to the Troubleshooting
section (Pages 8& 9) or call 1-800-665-8685.
